To all vwhom z r11/uy concerzw 1 Be it known that LCHARLES EDWIN BLUE,` a' citizen of the United States,l residingvat lVheeling, iu the county of Ohio'and State o fj West Virginia, have invented new anduse'ful' Improvements' in Machines for the Manufae' ture of Glassware, of which the following is' a specification. Y

My invention relates to improvements in machines for the manufacture of glassware, and pertains to that type of machinesin which' the`glass is pressed and then'expanded into itsy inished shape by a blowing operation.

One objectof my present invention is 'to provide a machine with a press-mold'andaj verticallymoving mold or moldsin which the pressed article is blown, the pressed article being transmitted from the press-mold to the blow-molti by suitable supports.

Another object of my present invention is to provide a stationary press-mold, an'eclz`V ring carrier, and a vertically-movable inold or molds in which the pressed article is blown,

. and a plurality of suitable supports adapted to support the neck-ring, whiehin turn supi-y ports the pressed article and by means of' which it is transmitted tothe blow position to be expanded in the blow-mold.

Another object loi my present invention pertains to a machine so constructed and arranged that themovement of lthe blow-mold carries the blow-head thereupon for blowing the pressed article.

My invention consists inthe construction and-arrangement off-parts, which-will be fully' describedhereinafter, and in whch- Figure 1 is a vertical sectional view taken on the dottedv line 1 1 of Fig. 2. Fig.` -2 is a horizontal sectional planview'taken on the 4.

dotted line 2 2 of Fig. 1. Fig. 3 is a detail sectional view of the blow-head and its valve. Fig. 4 is an inverted view of one end of the 7 neck-ring supports.

Referring now to the'drawings, A indicates a supporting-base, preferably supported upon wheels B, by means of which it is readily moved around as desired.

D is a support extending upward from one end of the base Aand to which the two parts' of the press-mold E are pivotedat their lower inner corners at the point a.. Situated below this press-mold E is a. motor for thepurpose sesamo. 679.131. (ramas.)

n of opening and closing the molds, which motor in this eventcomprises a cylinder F, carrying a piston G' anda piston-rod lIii, extending' `through itsv upperl end. Air is admitted to the opposite ends of this cylinder through the-pipes b, the admission of air to oppositeends thereof. being controlled through the medium'of a valve c, having at its lower end a treadle d. The operation of this part of the invention is wellunderstood and need not be particularly described.

Connected to the upper end of the pistonj rod Il is a cross bar or head I, to the opposite ends of whchthelower lends of links J are pivoted, theup'per ends of these links beingv pivoted to earsK, vprojecting .outward i'om v the upper ends of the two parts ofthe press moldlE.` From this construction 'it will be at o'nce understood that adownward movement ofthe piston-rod separates the' two parts of the pressmold, thus opening it, and an upward movement of the-piston-rod closes the Y two parts o'fjthe press-'mold ready to receive the charging and pressing operation.

' L is a `p1unger'rod, carrying atits lower end the usual plunger M for .pressing the' charged' Aglass within the press-mold, the said plunger-rod passingv upward and through a cylinder ANrearrying within thecylinder a piston P. Air is admitted to opposite ends of this cylinder-through the pipes e and iscontrolled through themedium of a valve f, having` 'at' its lower end -`ahandle g. The

operation of 'this 'part of my invention is also well understood for admitting air to either lend ofthe cylinder forraising or lowering the plunger.

Qlis a columnor standard projecting upward from the base A adjacent the standard D for the press-mold, and surrounding this column is a ring R. This ring is supported upon a collar S, which is .clamped in any lsuitablemann'er to the column Q, and this ring R is provided with a plurality of projeeting arms U, having their outer ends of a ringshape,'as shown at V. The under sides of these ringshaped portions are provided with jaws c', with which the neck-rings W are constructed to interlock for supporting the neck-ring throughthe medium of these arms U.A The neck-ring and these arms are provided with registering tongues and grooves,

2 ,Y .e17,94s

the said jaws 'i of the ring V forming the tongue and groove of that member to coact with the tongue and groove of the neck-ring. j is a standard projecting from' the opposite end of the base A, the said standard having a projection k, whichforms a bearing for the blow-mold table land around which the said table is adapted to rotate. Situated upon this table is' a plurality of blow-molds m, adapted to be opened and closed andV which may be of the usual form. The arms U, which support the neck-ring, are adapted to travel ina path which intersects the path of the blow-mold at the blowing position, whereby the neck.- ringl will` support the pressed article over the blow-mold'. i

The blow-mold table Z is also vertical-ly movable upon the standard j, as shown in dotted lines in Fig. 1, and this vertical movement is provided by means of any suitable motor or actuating element. In this instance ,I show the motor consisting of a cylinderp, carrying a piston q and a pistonrod r'. Air is admitted to the lower end of thiscylinder through'the pipe s, and the admission of the air is controlled by a valve t, actuated through the medium of a treadle u, as clearly .illustrated in Fig. 1. A standard 2 projects outward from the column'Q and is provided with a downwardlyprojecting arm 3 and an outwardly-project ing arm 4.' These arms form a support and guide for the blow-head rod 5, as shown, and intermediately pivoted to the outer end of the arm 4 is lever 6, one end of this `lever being pivotally connected with the blow-head rod 5 and the opposite end connected to the upper'end of a link 7, which in' turn has its lower end connected with a vertically-movable sleeve w, around which the `blow-table l rotates. The operation of' this part 'of my iuvention is that when the blow-table is elevated, as shown in solid lines in Fig. 1, the blow-head is depressed in position upon the top of the blow-mold, and air is automatically admitted through the construction ofthe blow-head, whichis fully shown and described in myPatentNo. 584,665, dated June 15,1897, and need not be more fully described herein.

The operation of my invention ,is as follows: The press-mold E is stationary, and of which there is but one, while there are a plurality of neck-rings and supports and also preferably a-plurality of blow-molds supported upon a rotating table. Glass is placed within the -press-mold at the pressing and charging point, as indicated in Fig. 2. The press-mold is then opened outward, leaving the pressed article supported by the ring and its'arm U. The blow-table is in its lowest position, and thispres'sed article is'carried around to the blow position by rotation of the arms U. When it reaches this`.point, the table l is moved upward, carrying the blowmold around the pressed blank or article, and in this movement of the press-mold the blow-head is carried to position and the artivthe discharging-point.

cl'e automatically blown. .A further movement of the ring-supporting arms, as indicated by arrow in Fig. 2, will disengage the arms from the blow-rings and then the blow-table is 'turned in the direction indicated by arrow and eithenlow'ered before or after it reaches A t the dischargingpoint the tu rning-ont boy opensthe mold, taking out the article and places Vthe l neck-ring upon lthe press-mold ready for another charging and pressing operation.l This operation is repeatedas is well understood. The rota'- tion of the supporting-arms'Uand the blow- 'mold table lis independent, and the arms U` are locked in proper position to coactwith the blow-mold Athrough'the medium 'of 4la pin. 0,

adapted to engage an opening in the collar S, the said pin being actuated through the lnedium of a handle 10 and its intermediate. rod 11 and bell-crankrlever' 12. The blow;table l is locked in its proper position through the medium of the 'levers 13, having their inner ends adapted 4to engage with the sleeve 2, which supports the blow-table I.

While I` here show and describe the pressmold as openingoutward and as hinged at its lower inner edge, it will be readil conceived that this mold may be made solid and be carried simply up and down through the movement of the piston-rod II without departing fromthe spirit and scope of my claims.

4While I have here shown duid-pressure motors for actuating'the press-mold and the blow-mold'supports, it will be readily..under-.

stood that any other form of motor or actuating member may be used without departing from the spirit a-nd scope oi.' my claims.

I claim, anddesire to secure by Letters Iatenti. i8*- 1. A machine for'tho manufacture of glassware, comprising apress-mold adapted to disengage the pressed blank, a laterally-movable blow-mold supported adjacent the pressmold,`a neck-ring adapted tocoperate with .the press-mold and to support the pressed blank, and a neck-ring support movable ina path intersecting both of said molds, substantially as described. e
